Development of Driver and Color Control System for High-Power RGB LED

A bilevel driving approach was proposed in the literature for mitigating the energy wastage associated with driving LEDs at high peak current. The main idea is to introduce two drive parameters, i.e., high/low PWM current levels and duty cycles, that give rise to a 2-D luminosity control capability. The same idea was later generalized to an n-level driving approach for maximizing the electrical...

Design and Application of a Photoacoustic Sensor for Monitoring the Laser Generated Stress Waves in Optical Fiber

Measurement of stress transients generated by a 400ns pulsed HF laser in an infrared fluoride glass fiber has been made using fast time – response piezoelectric film transducer. Acoustic signals up to 12 mV with frequencies ranging in megahertz generated by 21 mJ laser pulse when passed through the fiber axis in the linear region. It is shown that useful information such as onset of non - linea...

Design, Construction and Comparison of a Sensorless Driver Circuit for Switched Reluctance Motor

In the presented paper, a sensorless driver circuit is designed, constructed and tested to control two types of three-phase Switched Reluctance Motor (SRM). The presented control algorithm has three steps. In the first step, the SRM is controlled by an open-loop method. In the second step, mathematical model of the SRM phase, motor parameters and flux-current-rotor position relation are used in...

Secondary optical element design for intracorporeal LED illumination system.

In this Letter, we propose an intracorporeal illumination system for providing uniform and wide-field illumination during minimally invasive surgery. The illumination system is comprised of an Alexis wound retractor, a set of LEDs, and secondary optical elements (SOEs). The SOE was composed of a Fresnel lens and a total internal reflection lens, which was designed to improve the optical perform...
